Quizplus · Accepted Answer

The reticular activating system (RAS) is responsible for wakefulness and arousal. It receives sensory input such as the light of dawn and the sound of an alarm clock and sends output to other parts of the brain to stimulate wakefulness. The basal nuclei are involved in motor control and the limbic system is involved in emotions and memory. The cerebellar peduncles are involved in motor coordination.
